How do we know Christ's sacrifice is true?

The truth of Christ's sacrifice is grounded in both Old and New Testament Scriptures that prophesy His coming and His role as the sacrificial lamb. The Passover lamb points forward to Christ, who fulfilled this imagery in His own death. Furthermore, the New Testament presents the reality of His resurrection, affirming that His sacrifice was accepted by the Father as full atonement for sin. The historic witness of the apostles and the early Church also serves as a testament to the truth of Christ's atoning work, ensuring that it is firmly rooted in the revelation of God through His Word.
